Poppy - Google box breathing and you will find several videos explaining it. I feel they are helpful. I am going to make an appointment with an acupuncturist next week. Hope it helps with my breathlessness, insomnia and lightheadedness. I agree with you - after reading all these posts I also feel like I know more about long covid than my docs. They all say they don’t really know if all my problems are due to LC as there is not enough data on it yet. Very frustrating!

Hi @poppy67. Know what seems simple can be very difficult in this post covid world so hope ok I share a simple way of box breathing shared with me. Count to 4- slowly inhaling and allowing lower abdomen diaphragm to expand comfortably. Hold breath to same slow count of 4. Exhale slowly same count of 4 while drawing in diaphragm lower abdomen. Finally hold breath- same slow count of 4. These 4 moves would each create a side to form a square box🙂. I found this truly helps reset nervous system to help with so many symptoms and especially helpful middle of night or those difficult anxious times which are caused from our physical symptoms and not from us being anxious people that thank goodness most healthcare systems are finally recognizing. Best to you and all in this healing journey🌈
